Application filed August 12, 1839. Serial No. 320,524. (No model.)

To all whom it may concern.-

' Be it known that 1, WINsLow F. SAMPSON, a citizen of the United Statesof America, and a resident. of Goffstown, in the county of Hillsboroughand State of New Hampshire, have invented certain new and usefulImprovements in Heel-Burnishing Machines, of which t foilowin g is afull, clear, and exact description.

IO The machine of this invention consists, essentially, first, of areciprocating rotating carrier for a boot or shoe, adapted to clampthereto the boot or shoe at its heel, and so as to have the edge of theheel exposed and to have the I 5 heel eccentric to the axis of rotationthereof; second, of a continuously-rotating burnisher in position tohear on the exposed edge of the heel clamped and revolving as stated;third, of a frame at one end supporting the bur- 2c nisher and atitsopposite end adapted to swing and to be moved on a fixed support, andalso to hold the burnisher with an elastic and yielding pressure at abearing 011 the edge of the clamped heel, and all so that theburnishercan automaticallymoveinward and outward from the axis ofrotation of said carrier for the boot or shoe, and also can be moved to.

and fro across the edge and between the treading-face of the heel andthe upper of the boot 0 or shoe; fourth, of means for moving saidswinging frame which carries the burnisher forward and backward on itssupport, and thereby to move it and through itthe burnisher to and froacross the edge and between the treading-face of the heel and the upperof the boot or shoe; fifth, of means arranged on said swinging frame.carrying the burnisher and connected with the burnisher for rotating it,and which consists. in substance, of a pulley wheel of the burnisher,pulleywheels in two pairs and each pair arranged for separate andindependent rotation on said frame, and a belt common to onepulley-wheel of both of said pairs of pulley-wheels and leadingtherefrom to the pulley-wheel of the burnisher, and all so that withsaid pairs of pulley-wheels suitably driven in opposite directions bythen shifting said driving-belt for the burnisher from one to the otherof its driving pulley-wheel of said pair of wheels the rotation of theburnisher can be changed from one to another and opposite direction;sixth, of means for automatically shifting said driving-belt for theburnisher from one to the other of said driving pulley-wheels for saidbelt, and, seventh, of means for placing the burnisher into and holdingit in operative position on the edge of the clamped heel, in combinationwith means for automatically releasing said holding mechanism for thebur- 6o nisher, and thereby, under the reaction of its spring-pressure,heretofore referred to, on the burnisher, secure a removal of theburnisher from its operative position, and also at the same time securean automatic stop of the running of the machine in all its moving parts,except as to those parts through which the bu rnisher is rotated, as hasbeen explained.

The several essentials of the machine as above specially recited, exceptthat of rotation of the burnisher, are respectively constructed andotherwise arranged and combined in one machine, in substance, so thatduring one complete rotation of a common driving gear-wheel the clampedheel and in contact with the burnisher will be revolved for the wholelength of its edge to be burnished first in one direction and then inthe opposite direction. The burnisher while the heel is revolving in onedirection will be ro- 8o tated in one and a proper direction therefor,and while the heel is revolving in the other direction will be rotatedin the other and opposite and a proper direction, and at the same timeduring each direction of its rotation it will be moved frequently to andfro across the edge and between the treading-face of the heel and theupper, and the burnisher will be placed out of its operative position onthe heel-edge and the machine will be stopped 0 to be again placed inrunning connection and the burnisher in operative position on theheel-edge, all substantially as hereinafter described.

In the drawings forming part of this specication, the present improvedmachine for burnishing the edges of heels of boots and shoes isillustrated.

Figure 1 is a plan view. Fig. 2 is a front elevation. Fig. 2 is aview indetail, hereinafter referred to. Figs. 3 and a are elevations atopposite ends. Fig. 5 is a view in detail, as hereinafter appears. Fig.ti is a detail View, hereinafter referred to.

In the drawings, A represents the horizontal bed of the machine, to besupported (not shown) in any suitable manner.

B is the driving-shaft. This shaft is horizontal, and it is under therear portion, and extends from end to end, and is supported and turns insuitable fixed depending bearin g-blocks A A of the bed A.

B B are fixed and loose driving pulleywheels at the end portion of theshaft B, projecting beyond the right-hand end of the bed, and B is avertical pinion gear-wheel fixed on the other projecting end portion ofsaid shaft. The pinion B is at the rear of and meshes with a verticalgear-wheel B held and turning on a fixed horizontal stud B of thebearing-block A for the shaft B, which is at the left-hand end of thebed. The gear-wheel B has a radial slot B, at which by headed screw-boltand screw-nut B pivot-connection is made of one end of a pitman-rod Bwhich at its other end is pivoted and connected to the lower end of avertical arm 13, intermediately f ulcrumed and hung on a fixedhorizontal stud A of a post or upright A at the front side and left-handend of the bed and at its upper end portion having a segmental gear Bconcentric with the axis of stud A.

G is a vertical pinion gear-wheel at upper side of and meshing withsegmental gear B and fixedou the left-hand end portion of a horizontalshaft 0 turning in bearings of the upper end of the post A", andextending therefrom toward the right-hand end of the bed A, and at itssaid end portion it is offset, as at O to one side of its axial line,which line is in the vertical plane of the axial line of thefulcrum-stud A and also of pivot-connection of arm B with pitman-rod13*, when the arm and red are in their normal position, Fig. 1. Theoffset C of shaft 0 has an outer end face at right angles to its axisfor the rest of the boot or shoe (not shown, but placed upon and oversaid offset) at the inner surface of the heel portion of its sole, andwhich is held to its said rest by the pressure of a stiff springarm Chaving a plate 0" that bears on the treading-face of the heel and is atthe free end of said arm. The opposite end of the spring-arm is rigidlyheld on a radial arm C of the shaft C and the arm 0 between its ends hasa bow or curving shape, not only to accommodate the boot or shoe whenplaced between it and the shaft, as above explained, but also toincrease its spring and holding pressure.

The mechanism described constitutes of the machine of this invention themeans for holding a boot or shoe with the edge of its heel which is tobe burnished exposed and the means for a reciprocating revolution'of theheel so held about the axis of the shaft 0" holding the boot or shoebetween the opposite inner sole and outer treading-faces of its heel, ashas been explained. The reciprocation of the boot or shoe is securedfrom the continuous rotation of the driving-shaft B, working through thepitinan-rod connection B of it with the vertical arm B", having thesegmental gear 3 in mesh with the wheel 0 of the shaft carrying the bootor shoe, as explained.

By adjusting the pi\"ot-couneetion of pitman-rod B with the drivinggear-wheel B" at a greater or less distance from the center of rotationof said wheel the length of reciprocation of boot or shoe heel can bemade more or less, as may be required or desired to suit heels ofgreater or less length of edge-periphery between the opposite ends ofthe breast of the heel.

1) is the burnishing-tool. As particularly shown, this tool D is avertical wheel having a semicircular convex edge and otherwise formed orconstructed as well known for burnishing purposes. The bu rnisher D inoperation is at the upper side of the boot or shoe heel held, as aboveexplained, and it is fixed on one end of a horizontal shaft D having itsaxis parallel to the axis of the shaft 0 carrying the heel, and turningat opposite end portions in bearings D of one end ofthe frame I), theopposite end D of which is of a fork shape and is hung to swing througha vertical plane on a horizontal rod D, suspended at its opposite endportions on and extending across and between and free to be moved, ashereinafter appears, lengthwise through the upper ends of the upper andforked arms A of a fixed vertical post A at the rear side of the bed A.The axial line of the red I) is in a vertical plane parallel to thevertical plane of the shaft carrying the boot or shoe, and a planetoward the rear of the bed. The frame D", carrying the burnisher I), inits normal position is substantially horizontahand intermediate of itslength it rests on an adjustable screw-collar E of a verticalscrew-threaded rod E which passes upward through a suitable guide-hole(not shown) of the frame D, and at its lower end is pivoted to ahorizontal lever-arm E, located under said frame D, and between it andthe bed and at its rear end fulcrumed on a fixed pin A of the post A' ofthe bed, at its forward end having a handle E for convenience inoperating it, and between its ends normally engaged and held againstupward movement by a latch-catching mechanism, particularly shown indetail, and enlarged, Fig. 5, and to be hereinafter described, andagainst upward movement, because of the tension of a vertical coiledspring at its 0pposite ends, connected to it and said frame D, restingon the collar E, as above explained.

F is a vertical pulley-wheel 011 and located between the opposite endbearings of the F of the two pairs of pulley-Wheels is connected by abelt, (not shown), so as to be driven in opposite directions, and thelarger pulley-wheels F F. have a belt F to connect them, either one orthe other, according as the belt is placed on one or the other, with thepulley-wheel F of the burnisher-shaft D and thereby to rotate theburnisher, but in one direction when the belt F is on the pulley-wheel Fand in the other andopposite direction when said belt is on the otherpulley-wheel F and the belt is automatically shifted from onepulley-wheel F to the other F", and vice versa, as will hereinafterappear.

The rod D, having the frame D carrying the burnisher, swung on it, asexplained, is extended from its said supports A toward the left of thebed, audits outer end portion 1) is screw-threaded and receives ascrewthreaded collar G, having a hand-wheel G2 for convenience inturning it, and thereby to adjust it lengthwise on said rod, for apurpose as will hereinafter appear. This collar G has a peripheralgroove G which at opposite horizontal diametrical points is engaged bythe upper fork-shaped end of a vertical lever-arm G which is hung on afixed horizontal fulcrum pin or stud A of an upright Y A of the bed, andat its lower end is hung on a crank-pin G of a vertical disk G held on ahorizontal shaft G turning at its opposite end portions in bearings ofsaid upright A and of a companion upright A of the bed, and between saiduprights carrying a vertical ratchet-wheel G G is a gravity-pawl toengage the teeth of the ratchet-wheel G at its upper side. This pawl G9is fnlcrumed on the upper end of a vertical arm G which intermediatelyof its length is fulcrumed on a shaft G and at its lower end is pivotedto one end of a horizontal arm G and has the other end hung on acrank-pin G12 at one end of a horizontal shaft G turning at its oppositeend portions in bearing-blocks A of the bed A, and at its end oppositeto its end connected to arm G, as just stated, having a vertical bevelgearwheel G The vertical planes of the shaft G of bevel gear-wheel G andthe shaft G7 of the ratchet-wheel G are parallel and at right angles tothe rod D on which is hung the frame D carrying the burnisher, and alsoat right angles to the axis of rotation of the burnisher D and the shaft0 carrying the boot or shoe heel.

H is a vertical bevel gear-wheel meshing with the vertical bevelgear-wheel G before referred to, and carried by a horizontal shaft Hturning at its opposite end portions in bearing-blocks A of the bed A,and having its axial line parallel with the axis of rotation of theburnisher D and of the shaft 0 H is a crank-arm at one end and the upperside of the shaft H and H is a pitmanrod pivotally connected to saidcrank-arm and to the vertical lever-arm B, by which the held boot orshoe is oscillated, as has been explained, and intermediate of thefulcrum A of said lever B 011 the post A and the connection thereof withone end of the pitmanrod 13 and which at its opposite end is connectedto the driving gear-wheel B In the practical operation of the machineand under a continuous rotation of the driving-shaft B and through themechanism connecting it and the frame D carrying the burnisher D, as hasjust been explained, the burnisher is moved rectilinearly to and fro ina line parallel to its axis of rotation,or,in other words, to and fro ina direct line across the edge and either from the treading-face of theheel toward the upper or vice versa. The mechanism directly securingthis to-and-fro movement of the burnisher D consists of the rotatingratchet-wheel G and crank-connection with the fulcrumed arm G engagingthe rod D, on which the frame D carrying the burnisher, is hung. Theratchet-wheel is actuated or rotated by the pawl G which is movedforward, carrying the ratchet-wheel with it, and then backward over thewheel by the vibratory movement of the vertical leverarm B actingthrough the mechanism described, and which connects said arm B with thevertical lever-arm G carrying the pawl G Further than the above, thecoiledspring connection E between the frame D carrying the burnisher D,and the handle-lever E, with said lever secured as has been explained,gives the burnisher yielding and elastic pressure on the heel-edge whichis being burnished by it, and also allows the burnisher to move withingiven limits outward and inward to accommodate itself to the Varyingdistances of the edge of the heel from the axis of rotation of itscarrying-shaft O as the heel, because of being held on an offset of saidshaft, revolves around its axis.

J is a radial or crank arm fixed on and projecting downward from thehorizontal shaft H and at the end opposite to its end 0011- nected, asdescribed, to the driving gearwheelB".

J is a pitman-rod at one end pivotally connected to crank-arm Jand atthe other end to a crank-arm J projecting from the underv said arm andin position to engage a ratchet ITS 4 aaaozi wheel J at its upper side.The ratchet-wheel J turns on the horizontal shaft J and ithas fixed toit a collar J, provided at opposite diametrica-l points with two radialprojecting fingers J J in position as the collarand the ratchet-wheelare rotated to abut one after another against the upper side of ahorizontal foot or treadle piece J of a vertical angular lever J J,fulcrumed at its angle J on a post A of the bed A. This angular level-JJ at the upper end of its vertical arm J has an under shoulder J for therest and upward bearing of a latch-arm J of a horizontal lever Jfulcrumed at A on a'post A of the bed, and its latch-arm J is connectedby a vertical rod J with the handlelever E which, as before explained,is connected to the frame D", carrying the burnisher. Again, thishorizontal lever J is extended into a position overthe upper side of theloose and fixed pulley-wheels B B of driving-shaft B, and adapted (butwhich is not particularly shown, for the reason that it is well known)to act as a shipper to the driving-belt (not shown) of said pulleys, andthereby to move the belt from one pulley to the other by the swing ofsaid lever J in either one or the other direction, and so place themachine, through its driving-shaft B, either into or out of connectionwith the driving-power used. \Vith the catch-arm J of lever J engagedwith the angular lever J J as has been explained, the belt (not shown)for driving shaf t B is on the fixed pulley of said shaft, and with saidcatch-arm disengaged from the angular lever J J said belt is on theloose pulley. Again, with the catch-arm J of lever J engaged with theangular lever J J the handle-lever 11 is also held fast, and theburnisher D is in its proper field of action and bearing 011 the edge ofthe heel of the boot or shoe held on the shaft C as explained, and it isalso under the tension and elasticity of the spring E and with saidcatcl1-arm disengaged from the angular lever J J the bandle-lever J 3and frame D, carrying burnisher, are both free to swing upward from thereaction of the spring E and thereby the burnisher is placed out of itsfield of action and bearing on the edge of the heel held on the shaft 0The angular lever is disengaged from the catch-arm J of the lever Jtwice in each rotation of the ratchet-wheel J and by the operation ofthe finger-pieces J carried by said ratchet, on the foot or treadlepiece J of the angular lever J J, as has been hereinbefore more or lessparticularly alluded to. The angular lever J J is automatically engagedwith the catch-arm J of lever J by the action of a bent spring J", Fig.5, properly applied to the lever,provided said catcharm J issufliciently depressed therefor, its said depression being convenientlysecured by pressing or pulling down on the handle-lever E Theratchet-wheel J makes one-half of a rotation during one half and remainsstationary during the other half of a complete rotation of the bevelgear-wheel H, and the collar J, carrying the operatingpawl J and theshaft J 5 of said collar during the meantime vibrate in oppositedirectionsthat is, forward and backward through onehalf of a rotation.The vibratory shaft J carries an arm K, projecting radially upward fromit, and this arm at its upper end portion has two pins K K projectinghorizontally from one face thereof.

K' is avertical rod passing, Fig.3, between and upward above the pins KK of said arm K, and thence horizontally, as at K Figs. 1 and 2, andagain vertically, as at K, Figs. 2 and 3, directly through the thicknessof the frame I), carrying the burnisher, so as to turn at said verticalportion K in said frame, but by collars K K above and below said frame Dand fixed on said rod K to be held against vertical movement through theframe.

K K are crank-arms both fixed on the vertical portion K of the rod K KK, respectively above and below the frame D, carrying the burnisher.Each crankarm K K at its outer end K Figs. 1, 2, and 2*, is of forkshape, and the fork of the upper crankarm K Figs. 2, 3, and 4, extendsupward and that of the lower crank-arm K, Figs. 2, 3, and 4, extendsdownward, and both are in position to embrace the width of thedrivingbelt F for the pulley-wheel F of burnisher, and thereby under theswing of the vertical portion K of the arm K K K in one or the otherdirection on the frame D to swing said crank-arms K K in adirectioneitherto move the belt from the pulley-wheel F onto the pulley F or fromthe pulley F onto thepulley F as the case maybe. The swing of the arm K'K K, as has just been stated, is caused by the abuts ment of either pinK K carried by the shaft J as explained, against the vertical portion Kof said arm, and which portion K together with the horizontal portion Kconstitutes a crank-arm swinging by the vertical continuation K thereofin the frame D The mechanism just above described in the practicaloperation of the machine as a whole, and which operation is to bepresently explained, secures the shifting of the belt F from onepulley-wheel F to the other pulleywheel F or vice versa, and thus areversing of the direction of rotation of the burnisher D, because ofthe opposite direction of rotation of the pulley-wheels F F.

Further than as has been explained, the machine of this inventioncomprises a mechanism for withdrawing the spring-arm C confining, asexplained, a boot. or shoe at its heel in place for its edge to beburnished, and securing it out of and for setting said arm free toreturn to its operative position! This mechanism, Fig. 2, moreparticularly consists of a horizontal eye or staple L, held on andprojecting from the right-hand vertical portion of the spring-arm G avertical and angular catch-lever or hook L L Figs. 2, 2 and 3,to engagesaid eye, and a vertical bell-crank arm or lever L L carrying said catchL L and adapted to be operated from a treadlelever, (not shown,) andwhich is connected to it by a vertical rod L The catch L L is fulcrumedat its angle on the upper end of the vertical arm L of the bell-crankand with its hook-arm L uppermostand the open side of the hook towardthe spring-arm C and the other arm L projecting horizontally toward theright and at its outer end connected by a coiled spring L to thebellcrank, and the bell-crank is fulcrumed at its angle L on the upperend of a post or upright A of the bed A and has its arm L horizontal andextended toward the spring-arm C and at the outer end of said arm Ltreadleconnection is made, as has been explained. Both the angularcatch-lever and bell-crank at rest and in their normal position arevertical,-and by pulling down on the treadle-connection rod L thebell-crank, with its angular lever-catch, is carried toward and thecatchhook brought into engagement with the eye of the spring-arm G onwhich by the then continued movement of the parts in the same directionthe spring-arm O engaged with them, as stated, is pulled away from itsoperative position, to be there made fast, if so desired-as, forinstance, by any suitable device (not shown) with which to fasten thebell-crank against its return from the reaction of a spring (not shown)suitably applied to it therefor.

The operation of the machine described and as a whole is as follows: Theboot or shoe which is to have the edge of its heel burnished (first,however, having, as hereinafter explained, drawn the spring orheel-clamping arm C back by means of the lever-catch L L and itsoperating mechanism and, it being understood that the handle-lever E isfree and the burnisher out of operative position and the machine out ofconnection with the driving-power) is placed on and over the shaft G andthe inner face of its sole at the heel against the end face 0 of saidshaft, and then the spring clamping-arm O is released, and coming to abearing against the treading-face of the heel the boot or shoe isthereby clamped on the shaft 0 with its edge to be burnished exposed.lVith the boot or shoe held as stated and the heel and the machine inits several parts properly adjusted, all as hereinafter particularlyexplained, and the burnisher under rotation in the proper direction, thehandle-lever E is then by the operator pulled down sufficiently toengage it with the catch-lever J J which brings the rotating burnisheragainst the heel-edge and connects the driving-shaft B of the machinewith the driving-power used, and thus, the machine being set in motionand the burnisher brought into contact with the edge of the heel, theheel is revolved first in one direction and then in the other direction,carrying its edge forward and backward from one end to the other end ofits breast under the burnisher, which at the same time is moving inwardand outward to suit the varying positions of the heel edge relative tothe axis of rotation of the shaft 0 carrying the boot or shoe, also isbearing with an elastic and yielding pressure on the heel-edge, and isvibrating to and fro across the width of the edge of the heel betweenits treading-face and the upper, and, furthermore, is changed in itsdirection of rotation when theheel is at either end of its saidreciprocating revolution, and so on until from the continued running ofthe machine the lever-catch J J is released from its hold of thehandle-lever E by the operation thereon of one or the other, as the casemay be, of the finger-pieces J J carried by the rotating collar Jwhereupon the drivingbelt (not shown) is shifted from the fixed to theloose driving-pulley of the driving-shaft B, stopping the running of themachine and placing the burnisher out of operative position.

In the operation of the machine, as has been explained, the oscillationof the segmental gear B secures, by the pitman-rod H and crank-arm Hconnection of it and of the horizontal shaft H, a rock of said shaft Hand thus, by the described connections of said shaft and of theratchet-wheels G J a stepby-step movement of each of said ratchets and arock of the'arm K. The step-by-step movement of the ratchet-wheel Gsecures a vibratory movement of the burnisher across the edge betweenthetreading-face of the heel and the upper, and the step-by-stepmovement of the ratchet-wheel J 8 secures a release of lever-catch J Jand thereby a stop of the running of the machine in all its parts,(excepting, however, as to the parts for rotating theburnishen) and aplacing of the burnisher from contact With the edge of the heel and therocking of the arm K secures a shifting of the driving-belt F for theburnisher from one to the other of the driving-pulleys F F The operativeparts are adjusted for a length of oscillation of the heel equal to thelength of the edge of the heel from end to end of the breast. thereof,also for the direction of rotation of the burnisher to be changed at theend of each oscillation of the burnisher, and for a stop of the runningof the machine and a placing of the burnisher out of contact on a givennumber of oscillations of the heel under the burnisher. The manner ofmaking these several adjustments, it is believed, is obvious from thedescription already given without further particular explanation.

The parts of the machine for releasing the clamping-arm C from the heelare worked by pulling the rod L down, which swings the catch-hook L Lover toward and engages it with the eye L of the clamping-arm 0 so thaton the continued downward pull on said rod said arm is drawn backward,releasing the boot or shoe for its removal from and for the placing ofanother heel on the machine, on

which, releasing the rod L, the clamping-{nan C isleft free to clamp theboot or shoe, as before, and the catch-hook L L to disengage from it andto return with all connecting parts to its and their normalpositious,Fig. 2.

As particularly shown and described, the machine is stopped twice foreach rotation of the disk or collar J", carrying the fi tiger-pieces Jand, as is plain, with a single finger-piece the machine would then bestopped once only for each rotation of said disk or collar, and withthree or more finger-pieces at equal or unequal distances apart themachine would then be stopped three or more times, according to thenumber of linger-pieces for each rotation of said disk or collar.

The rod D through which, as has been described, the carrier D for theburnisher is moved to and fro, is in separate lengthwisetelescopingparts I) I), Figs. 1 and 2, and the part D and upper forked end ofleverarm (l engaging screwmut G, are connected by a red I)", that at itsopposite ends is pivoted to the part D and arm G, all so that bysuitably turning the screw-nut the part D is moved either in or out, asthe case may be, on the part D shortening-or lengthening the rod D as awhole, and thereby to adjust the burnisher and to insure its movement toand fro across the edge of the heel between the treadingface thereof andthe upper and fully to the upper, and also to center the belt shiftingdevice described relative to thedriviug pulley-wheels F I for theburnisher.
